SPECIFICATION forming part of Letters Patent No.. 685,575, dated October24, 1899.

Application filed February 16,1899. Serial No. 705,649. (lilo model.)

' T0 all wil/0m t may concern:

Be it known that I, ELMER MCHUGH, of Lambertville, in the county ofHunterdon and v State of New Jersey, have invented a new and usefulImprovement in Vehicle Hubs, ,of which the following is a full, clear,and exact description.

The object of my invention is to provide a means whereby an elasticcushion may' be made to form a portion of the hub or constitute ayielding bearing for the axle or a yielding connection between the innersurface of the hub and the axle.

A further object of the invention is to accomplish the results abovementioned in a simple, durable, and economic manner and yet enable a hubhaving the improvement applied to be readily removed from the axle.

The invention consists in the novel construction and combination of theseveral parts, as will be hereinafter fully set forth, and pointed outin the claim.

Reference is to be had to the accompanying drawings, forming a part ofthis specication, in which similar characters of reference indicatecorresponding parts in all the figures.

Figure 1 is a longitudinal section through a vehicle-hub, illustratingthe application of the improvement thereto. Fig. 2 is a longitudinalsection through the hub of a bicyclewheel having the improvement appliedthereto, the axle of the wheel being in side elevation; and Fig. 3 is atransverse section on the line 3 3 of Fig. 1.

A represents the hub of a vehicle, and B a sleeve for the interior ofthe hub, the said sleeve being preferably attached to the hub by meansof keys 10. An inner sleeve 11 is likewise provided for the hub, thesleeve 11 being adapted to lit over the spindle C of the axle, and theinner sleeve 11 is prevented from moving laterally by forming a collar12 on the laxle where it connects with the spindle and locating upon thethreaded outer end of the spindle a washer 13, held in position by a nut14.

The space between the inner and outer sleeves B and 11 is practicallyfilled by a cushion O'. This cushion is made of an elasticmaterial-rubber, for example-and while it may be made in one piece itmay be made in sections, if desired. The cushion C is not continuous,since a space is provided between its ends to admit of the expansion andcontractionof the cushion under conditions of wear, and for the samereason the outer ends of the cushion do not extend to the flange 12 ofthe axle and the washer 13, as shown in Fig. 1. Under such anarrangement the cushion is capable of expanding endwise as well as circumferentially. To facilitate this action, the walls of the sleeves 17 18,which walls engage the cushion, are made smooth, as shown in thedrawings.

In Fig. 2 I have illustrated the application of the improvement to thecrank-hanger of a bicycle, in which D represents the crankshaft, thesaid crank-shaft having a threaded surface 16 at each of its ends. Thecrankshaft D is held to turn in ball or roller bearings E, and a sleeve17 is made to surround the cone-casings of the roller or ball bearings,

and in connection with the sleeve 17, which may be termedl the innersleeve, correspondingto the sleeve 11, (shown in Fig. 1,) an outer orhub sleeve 18 is employed, corresponding to the sleeve B,vas illustratedin Fig. 3. lVashers 19 are made to engage with the outerface of thecones of the roller or ball bearings E, the said washers being looselyYfitted upon the shaft D, and the washers `are held in position by nuts20, that are secured upon the threaded portions of the shaft.

The cushion O2, corresponding to the cushion C', (shown in Fig. 1,)practically fills the space between' the inner and outer sleeves 17 and18. The cushion maybe in one piece, as

illustrated in Fig. 2, or, as heretofore stated,-

dent to the usual mountings of the wheels and,

that the cushions may be solid or pneumatic.

IOO

1o the cushion, an outer sleeve having a smooth Wall inelosing thecushion and lying snugly against the same, and means carried by the axleat each end of the hub and respectively bearing against the ends of thehub to cover the cushion.
